This was the conclusion of a study conducted by Roy Remme, Matthias Schröter and Lars Hein of Wageningen University, in collaboration with Bram Edens. The aim of the study was to develop knowledge about the monetary contribution of ecosystems to the regional economy.

For approximately 50 years, scientists have known there exists a large pool of dissolved carbon in the deep ocean, but they didn't know much about it—such as the carbon's age (how long it's been in organic form), where it came from, how it got there, and how long it's been there, or how these factors influence its role in the carbon cycle.http://phys.org/news/2015-02-carbon-mysteries-deep-ocean.html

A new study by INRA and Arvalis-Institut du Végétal turns this paradigm on its head.

Inspired by these creatures and looking to reduce atmospheric carbon dioxide levels, a team led by scientists at Pacific Northwest National Laboratory sought to mimic this process by a rational design of highly stable protein-like molecules (called peptoids). The team discovered that they could speed or slow calcium carbonate or calcite formation by changing the peptoid's structure and tuning its electric charge and affinity for water.http://phys.org/news/2014-11-nature-scientists-protein-esque-molecules-carbon.html

The new and improved methodology used to make the map marks a sea change for future market-based carbon economies. The new carbon map also reveals Perú's extremely high ecological diversity and it provides the critical input to studies of deforestation and forest degradation for conservation, land use, and enforcement purposes.

While no one has undertaken an accurate census, a spoonful of soil holds hundreds of billions of microbial cells, encompassing thousands of species. "It's one of the most diverse microbial habitats on Earth, yet we know surprisingly little about the identities and functions of the microbes inhabiting soil," said Jim Tiedje, Distinguished Professor at the Center for Microbial Ecology at Michigan State University. Tiedje, along with MSU colleagues and collaborators from the U.S. Department of Energy Joint Genome Institute (DOE JGI) and Lawrence Berkeley National Laboratory (Berkeley Lab), have published the largest soil DNA sequencing effort to date in the March 10, 2014, issue of Proceedings of the National Academy of Sciences (PNAS).

One of these is geoengineering: deliberate, large-scale intervention in the Earth's natural systems to counteract climate change. Understanding all of the possible effects of geoengineering, such as the results of iron fertilization on marine ecosystems, is vital. In iron fertilization, which has been discussed as a way to sequester carbon dioxide from the atmosphere, iron is introduced to the surface ocean to stimulate a phytoplankton bloom in locations where iron is the limiting nutrient. Carbon taken up by the phytoplankton is later sequestered in deep sea sediments.http://phys.org/news/2013-12-fate-bioavailable-iron-antarctic-coastal.html
